a

RNFL= retinal nerve fiber layer; GDx VCC= scanning laser polarimetry with variable corneal compensation; VF= visual field; 1/L = 1/Lambert; POAG= primary open angle glaucoma; PACG= primary angle-closure glaucoma; TSNIT= temporal-superior-nasal-inferior-temporal

b

rs = Spearman's rank correlation coefficient. Data are shown in global average and six corresponding measurement sectors.

c

P value for Spearman's rank correlation coefficient.

d

Pseudo R2 is from the multivariate median regression model adjusted for age, sex, axial length, and horizontal and vertical disc diameters.

e

Statistically significance: significance was set at P <0.05 for global correlations and P <0.0083 for each sector as the correction for multiple comparisons.
